[Java知识库]Spring Cloud学习记录之项目搭建

1、创建Spring Cloud项目

1.1 创建父目录

? ? ? ? ?首先选择File->New->Project->Maven（点击next）->填好GroupId和Artifactid（点击next）->再设置项目名字（点击next） 项目创建完成具体如下：

?

?

?然后复制pom.xml代码

 <packaging>pom</packaging>
    <!--模块名及描述信息-->
    <name>MineBlogSystem</name>
    <description>test system project for Spring Boot</description>
    <!--定义spring boot的版本-->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
    </parent>

    <properties>
        <java.version>1.8</java.version>
        <kotlin.version>1.5.31</kotlin.version>
        <spring-cloud.version>Greenwich.RELEASE</spring-cloud.version>
    </properties>
    <!--相关依赖-->
    <dependencies>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.2</version>
            <optional>true</optional>
        </dependency>
        <!--测试框架-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <!-- 标识 spring cloud的版本以及spring cloud alibaba的版本，由于spring cloud alibaba还未纳入spring cloud的主版本管理中，所以需要自己加入 -->
    <dependencyManagement>
        <dependencies>
            <!--<dependency>-->
            <!--<groupId>org.springframework.boot</groupId>-->
            <!--<artifactId>spring-boot-dependencies</artifactId>-->
            <!--<version>2.1.10.RELEASE</version>-->
            <!--<type>pom</type>-->
            <!--<scope>import</scope>-->
            <!--</dependency>-->
            <!--spring cloud alibaba的版本，-->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>0.2.2.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

然后再删除src目录如下图：

?1.2 创建Module

选中项目右键->选中new->Module->Maven（点击next）->添加Module的Artifactid（点击next）->填写Module名称(点击finish) 具体如下图：

?

?然后再当前module中的pom.xml中添加相关内容，具体如下：

 <version>0.0.1-SNAPSHOT</version>

    <!--相关依赖-->
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!--服务注册与发现-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
        <!--统一配置-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
        </dependency>
        <!---->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
        </dependency>
    </dependencies>
    <!--配置-->
    <build>
        <plugins>
            <plugin>
